The specific heat capacity of iron is greater than that of lead hence the iron will melt the ice more than the lead.
<h3>What is the specific heat capacity?</h3>
The specific heat capacity refers to the amount of heat that is required to raise the temperature of 1Kg of a body by 1 K.
We know that the specific heat capacity of iron is greater than that of lead hence the iron will melt the ice more than the lead.

4.5m/s you count the number between 6 and 14 and get 9 do 9 divided by 2 and you get 4.5 m/s increase. hope this helps.
Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Answer:
d_{b} = 2 d_{a}
Explanation:
The electrical resistance for a cylindrical wire is described by the expression
R = ρ L / A
The area of a circle is
A = π r²
r = d / 2
A = π d²/4
We substitute
R = ρ L 4 /π d²
Let's apply this expression to our case, they indicate that the resistance of wire A is 4 times the resistance of wire B
= 4 R_{b}
We substitute
ρ 4/π 
² = 4 (ρ 4/π d_{b}²)
1 / d_{a}² = 4 / d_{b}²
d_{a} = d_{b} / 2
